Saw blade type cave development machine

Abstract

The invention discloses a saw blade type cave development machine, which comprises a machine body, wherein the machine body is provided with wheels, a movable frame and a supporting frame; the movable frame comprises an upper bracket and a lower bracket, the front end of the upper bracket is provided with a rotating shaft, a saw blade is fixed on the rotating shaft, and a motor is connected on the rotating shaft; the rear end of the upper bracket is coupled at the top of the lower bracket, and the bottom of the lower bracket is supported on the machine body; the saw blade supporting frame is supported at the bottom of the upper bracket, and the bottom of the saw blade supporting frame is supported on the machine body; and a push rod is connected at the joint of the brackets, the front end of the push rod is coupled at the joint of the brackets, and the rear end of the push rod is connected on the supporting frame by screw threads. The saw blade type cave development machine has the advantages of simple structure, low production cost, low operating vibration and low damage; a saw blade and a hammering machine of the development machine can be adjusted up and down, left and right, so the development machine is flexible, simple and convenient to operate and can be used on different terrains; and the development machine does not need to use explosive, and can control the size of the crushed ores during excavating so as to improve the value of the ores and reduce environmental pollution.

Description

technical field [0001] The invention relates to a tunneling machine, in particular to a saw blade type cave boring machine used in mining. Background technique [0002] When mining, it is necessary to dig a tunnel into the mine. At present, when excavating tunnels, most of them are manually excavated, or explosives are used to blast rocks, which requires a lot of manpower, and the efficiency of tunnel excavation is also slow, and the use of explosives will also cause harm. Now some places use tunnel boring machines, although it saves manpower, but the current tunnel boring machines are heavy in structure, high in cost, and cannot operate flexibly when excavating tunnels, as disclosed in the Chinese patent application (application number is 200710044689.8). A tunnel boring machine, the structure adopts shield type, expensive, bulky, inconvenient to move, and only suitable for digging in soft soil, not suitable for mining. Currently, the tunnel boring machine used in m...

Problems solved by technology

At present, when excavating tunnels, most of them are excavated by hand, or explosives are used to break rocks.

Now some places use tunnel boring machines, although it saves manpower, but the current tunnel boring machines are heavy in structure, high in cost, and cannot operate flexibly when excavating tunnels, as disclosed in the Chinese patent application (application number is 200710044689.8). A tunnel boring machine, the structure adopts the shield type, which is expensive, bulky, inconvenient to move, and only suitable for digging in soft soil, not suitable for mining

Currently, the tunnel boring machine used in mining, such as the crushing tunnel boring machine disclosed in the Chinese patent application (application number 200710158849.1), uses a drill bit to crush the stones in the tunnel and then transport them out. The obtained ore is crushed, and there is no block, which reduces the value of the stone ore. For some ores (such as fluorite, carving stone), it will cause greater losses, and the crushed stone debris will also flow into the river. Affect water quality, pollute the environment

In addition, this kind of crushing roadheader also has the disadvantages of high cost, heavy structure, and inflexible operation. The adjustment of the up and down angle of the drill bit is realized by a hydraulic cylinder, which is high in cost and consumes a lot of energy, and the drill bit cannot be adjusted left and right.
